Comtech EF Data (News - Alert) Corporation announced today that it will preview the new
CDM-760 Advanced High-Speed Trunking Modem at the AfricaCom 2012 show in
Cape Town, South Africa next week. The CDM-760 builds on Comtech EF
Data's award-winning family of high-speed trunking modems, and was
designed to be the most efficient and highest throughput point-to-point
trunking modem. It provides ultra wide band symbol rates, near
theoretical performance with minimal implementation loss, the DVB-S2
Efficiency Boost technology, Super Jumbo Frame Ethernet support and
other value-added features.

The CDM-760 Advanced High-Speed Trunking Modem supports symbol rates of
1 ksps to 150 Msps and data rates up to 314 Mbps simplex and 628 Mbps
duplex. Demonstrating an industry breakthrough, these astounding data
rates can be achieved when using 8PSK, 16APSK or 32APSK modulation. When
coupled with the native Super Jumbo Frame Ethernet interface, the
CDM-760 can process Ethernet frames at greater than 1.2 million packets
per second.

DVB-S2 EN 302 307 is widely accepted as the most spectrally efficient
standards-based waveforms. The new CDM-760 features an enhancement to
DVB-S2 with its proprietary DVB-S2 Efficiency Boost (DVB-S2-EB1)
waveforms. The CDM-760 essentially doubles the number of available
MODCODs, introduces three new rolloff figures (5%, 10% and 15%), and
minimizes implementation loss to near theoretical operation. The result
is a 10-35% increase in spectral efficiency compared to the DVB-S2
standard, without increasing power or occupied bandwidth. The DM-760 is
software upgradeable to support future standards including DVB-S2
Efficiency Boost, DVB-S2 Extension and DVB-S3.

The CDM-760 offers additional features that enable OPEX (News - Alert) reduction and
the best possible use of satellite link resources, including Adaptive
Coding and Modulation operation, premier encapsulation methods, and the
powerful DoubleTalk® Carrier-in-Carrier® bandwidth
compression that allows transmit and receive carriers of a duplex link
to share the same transponder space.

"By using this combination of advanced technologies and innovative
architecture to support high-speed trunking, ISPs and telco operators
can achieve unparalleled space segment efficiencies and minimize
unnecessary overhead for satellite links," commented Daniel Enns, senior
vice president marketing and business development.

Innovative Features Mean Major Savings for Cellular Operators Using Satellite BackhaulWith the rising cost of satellite bandwidth and the need for more of it to support an ever increasing number of voice, data and now video services, operators must seek ways to reduce both their hardware investment costs and operating expenses, especially when fierce competition forces them to provide these new services without raising their rates.
